Strange exception found

Description

When I analyse the following contract, Mythril finds an assertion violation that does not seem to be correct. Is that correct?

RoomThermostat.sol is as follows.

pragma solidity >=0.4.25 <0.5.16;

contract RoomThermostat
{
    //Set of States
    enum StateType { Created, InUse}
    
    //List of properties
    StateType State;
    address Installer;
    address User;
    int TargetTemperature;
    enum ModeEnum {Off, Cool, Heat, Auto}
    ModeEnum  Mode;
    
    constructor(address thermostatInstaller, address thermostatUser) public
    {
        Installer = thermostatInstaller;
        User = thermostatUser;
        TargetTemperature = 70;

       assert(State == StateType.Created);
    }

    function StartThermostat() public
    {
        if (Installer != msg.sender || State != StateType.Created)
        {
            revert();
        }

       assert(State == StateType.Created);

        State = StateType.InUse;

       assert(State == StateType.InUse);
    }

    function SetTargetTemperature(int targetTemperature) public
    {
        if (User != msg.sender || State != StateType.InUse)
        {
            revert();
        }

       assert(State == StateType.InUse);

        TargetTemperature = targetTemperature;

       assert(State == StateType.InUse);
    }

    function SetMode(ModeEnum mode) public
    {
        if (User != msg.sender || State != StateType.InUse)
        {
            revert();
        }
       assert(State == StateType.InUse);

        Mode = mode;

       assert(State == StateType.InUse);
    }
}

How to Reproduce

I am using solc 0.5.10.

Run the following command: myth analyze --modules Exceptions RoomThermostat.sol

For example:

==== Exception State ====
SWC ID: 110
Severity: Medium
Contract: RoomThermostat
Function name: SetMode(uint8)
PC address: 895
Estimated Gas Usage: 3824 - 5239
An assertion violation was triggered.
It is possible to trigger an assertion violation. Note that Solidity assert() statements should only be used to check invariants. Review the transaction trace generated for this issue and either make sure your program logic is correct, or use require() instead of assert() if your goal is to constrain user inputs or enforce preconditions. Remember to validate inputs from both callers (for instance, via passed arguments) and callees (for instance, via return values).
